Integumentary System Assessment — Nursing Notes

1. Learning Objectives

By the end of this material, you should be able to:

1. Define terminology related to assessment of the integumentary system.

2. Describe the anatomy and physiology of the integumentary system.

3. Identify equipment needed to assess the skin, hair, and nails.

4. Identify positioning for an integumentary examination.

5. Identify techniques used to assess the integumentary system.

6. Explain the process of performing an integumentary assessment.

7. Recognize expected findings and identify unexpected findings.

2. Integumentary System Overview

The integumentary system includes:

• Skin

• Hair

• Nails

The skin is the body's largest organ and provides an important protective barrier between the body and the environment.

Major functions

According to your notes, the integumentary system provides:

Protection

The skin protects underlying tissues from the environment and helps provide a barrier against injury and harmful substances.

Temperature regulation

The skin participates in maintaining body temperature.

Sensory perception

The skin contains structures that allow the body to detect sensations.

Excretion

The integumentary system contributes to the excretion of waste and toxins.

Vitamin D production

The skin participates in the production of vitamin D.

Easy memory:

P-T-S-E-D

• Protection

• Temperature regulation

• Sensory perception

• Excretion

• D = Vitamin D production

3. Anatomy of the Skin

The skin has three major layers identified in your material:

Epidermis

The epidermis is the outer layer of the skin.

It provides an important protective barrier.

Dermis

The dermis lies beneath the epidermis.

It contains structures involved in sensation and other skin functions.

Subcutaneous tissue

The subcutaneous tissue lies beneath the dermis.

It provides support and cushioning beneath the skin.

Remember:

Epidermis → Dermis → Subcutaneous tissue

Think:

E → D → S

4. Nails

Nails are described in the material as:

• Clear

• Hard plates of keratin

During assessment, inspect the nails for:

• Color

• Shape

• Symmetry

Also assess for abnormalities such as clubbing.

5. Subjective Assessment

Subjective data is information obtained from what the patient reports.

Ask about:

Previous skin conditions

8. Equipment

Your pasted material does not provide a specific equipment list. For a basic integumentary assessment, the nurse generally needs equipment appropriate to the assessment being performed.

Common equipment includes:

• Good lighting

• Gloves when indicated

• Penlight if needed for close inspection

• Measuring device/ruler when measuring a lesion

• Documentation equipment

Important

The most important "equipment" for routine assessment is often adequate lighting and your ability to inspect and palpate systematically.

9. Positioning

Position the patient so that the area being assessed is:

• Easily visible

• Easily accessible for palpation

• Properly exposed while maintaining privacy

Nursing considerations

• Provide privacy.

• Expose only the area being assessed.

• Maintain patient dignity.

• Reposition the patient as necessary to inspect all relevant areas.

• Use appropriate draping.

The exact position depends on which area of the skin, hair, or nails is being examined.

10. SKIN COLOR

Skin color should be assessed during inspection.

Your material specifically identifies:

• Jaundice

• Cyanosis

• Pallor

• Erythema

• Vitiligo

• Senile lentigines

as important findings to recognize.

11. Jaundice

Jaundice is a yellow discoloration of the skin.

Assessment

Look for yellow discoloration of the skin and other visible tissues.

Key word:

Jaundice = yellow

12. Cyanosis

Cyanosis is a bluish discoloration.

Key word:

Cyanosis = blue

It is an unexpected finding requiring further assessment.

13. Pallor

Pallor means unusually pale skin.

Key word:

Pallor = pale

It is an unexpected finding that should be assessed in context with the patient's overall condition.

14. Erythema

Erythema is redness of the skin.

Key word:

Erythema = red

It may be seen with irritation or inflammation and should be assessed along with other findings.

15. Vitiligo

Vitiligo is a condition characterized by areas of decreased or absent skin pigmentation.

It may appear as lighter or depigmented areas of skin.

16. Senile Lentigines

Senile lentigines, also called solar lentigines, are areas of increased pigmentation commonly associated with aging and sun exposure.

Your material identifies them as a finding to recognize during skin inspection.

Remember:

Senile/solar lentigines = pigmented spots associated with aging/sun exposure

17. MOISTURE

Inspect the skin for:

• Excessive dryness

• Excessive moisture

The patient's history should also include questions about changes in skin moisture.

18. PRURITUS

Pruritus means itching.

The patient may report:

• Generalized itching

• Localized itching

• Persistent itching

• Itching associated with a rash or lesion

Pruritus is a subjective symptom, meaning the patient reports it.

19. SKIN TURGOR

Turgor refers to the skin's elasticity.

It is assessed through palpation.

Skin turgor can provide information about hydration status.

20. TENTING

Tenting occurs when the skin remains elevated after being pinched and released instead of quickly returning to its original position.

It is an unexpected finding that can be associated with decreased skin elasticity and may indicate dehydration, depending on the patient's age and clinical situation.

Memory:

Normal → skin returns

Tenting → skin stays elevated

21. EDEMA

Edema is swelling caused by excess fluid in tissues.

The material specifically identifies edema as part of skin inspection.

It can also be assessed through palpation.

22. PITTING EDEMA

Pitting edema is edema in which pressure applied to the skin leaves an indentation.

Assessment

The nurse palpates the affected area and observes whether an indentation remains after pressure is released.

23. LESIONS

A lesion is an abnormal area of tissue.

Your material emphasizes identifying and describing lesions.

When assessing a lesion, consider:

• Location

• Color

• Size

• Shape

They are identified through inspection.

37. ECCHYMOSIS

Ecchymosis is a larger area of bleeding under the skin, commonly appearing as a bruise.

Comparison:

Petechiae = tiny pinpoint areas

Ecchymosis = larger bruise-like area

38. HEMATOMA

A hematoma is a localized collection of blood outside the blood vessels.

It may appear as a localized swollen or discolored area.

Important comparison
